Problems solved by technology

For example, one of the generators in a parallel system may operate under relatively more severe conditions than one or more of the other generators and thus suffer relatively greater cumulative damage, whereby it is relatively more prone to damage during system operation malfunction
Continued business-as-usual reliance on generators that have a relatively high probability of failure, which may unpredictably and inconveniently lead to their need to be replaced or repaired
Moreover, unpredictable failure of such generator units can undermine system reliability at times when parallel generator systems are under high system load conditions when all generators in the system may be operating, albeit temporarily

Embodiment Construction

[0029] The embodiments of the invention described below are not intended to be exhaustive or to limit the invention to the precise forms disclosed in the following detailed description. Rather, the embodiments were chosen and described in order to enable others skilled in the art to understand and understand the principles and practice of the invention.

[0030] figure 1 An example parallel generator system embodiment connected to an electrical load is schematically shown. The depicted system 20 includes a master controller 22 , and four parallel-connected generator units 24 , designated G1 , G2 , G3 , and G4 , each with its own generator controller 26 . As discussed further below, the inclusion of the master controller 22 is optional; the generator controller(s) 26 of a generator unit 24 or of a plurality of generator units 24 may be adapted to perform the loads disclosed herein. share the balance method. The generator units 24 may generally be driven by a single prime mov...
